Kajian Defoliasi Sorgum Pada Tumpangsari Dengan Kacang Hijau*)

Study on Defoliation of Sorghum under Cropping Pattern by Mungbean. The aim of the research was to find out the effect of defoliation of sorghum under cropping pattern toward the yield of sorghum, Mungbean and total relative result of the best sorghum and Mungbean in intercropping system has been carried out in Kebun Percobaan Fakultas Pertanian Universitas Gadjah Mada in Banguntapan, Bantul Regency from February up to June 2006. The research method used was split plot design with 2 factors and 3 repetitions. The main factor was defoliation of sorghum comprising of 2 levels: sorghum defoliation (D1) and without sorghum defoliation (D2). The sub factor of sub was cropping pattern, comprising of 5 levels: monoculture of Mungbean (H100). 75% sorghum: 25% Mungbean (S75 H25), 50% sorghum: 50% Mungbean (S50 H50), 25% sorghum: 75% Mungbean (S25 H75) and monoculture sorghum (S100). The results of the study showed that 1) the defoliation sorghum did not affect the yield of mungbean and sorghum, 2) cropping pattern of mungbean monoculture resulted bean/plant amount, seed/plant weight and seed weight/ha of mungbean as higher compared to other cropping pattern, 3) cropping pattern of 25% sorghum: 75% mungbean resulted seed weight/malai sorghum was higher compared to other planting patterns and the highest seed weight/ hectare was resulted in sorghum monoculture planting pattern, 4) the highest total relative yield was 1,303 given planting pattern at 50% sorghum: 50% mungbean and 5) the form of the relation between sorghum and mungbean in intercropping pattern and sorghum defoliation was complementary, while intercropping and without sorghum defoliation was supplementary

MONOLITH HOLLOW FLOORS FOR DWELLING HOUSES

This work summarizes monolith cellular floors design and construction within the site of a residential apartment house. The questions of engineering design, reinforcement and erection technology are considered. Attention is paid to the construction arrangement, workers training, technical and economic effectiveness of the approach compared to the similar procedures used for solid reinforced concrete floors

The Kenyan environment's influence on the emergence and development of corporate entrepreneurship among SMEs

What environmental factors enable corporate entrepreneurship (CE) among African SMEs. CE helps firms to recognize and exploit new opportunities, and is particularly valuable for forms in turbulent, dynamic, or highly volatile environments of Africa. However, to date there is a dearth of research which considers the unique features of the African environmental context and their influence on the CE. To address this gap in our empirical knowledge, this study draws on Institutional Theory to examine the influence of the external environment on the emergence and development of CE among African SMEs. Given the exploratory nature of the study, a multiple case study approach was adopted. Five SMEs from Kenya's services sector formed the basis for empirical enquiry. Kenyan entrepreneurial attitudes and values along with increasing market and environmental dynamism were found to condition the emergence of CE activities among SMEs, while individual and firm-level networks and social capital, as well as deregulation of the Kenyan environment and government support initiatives were perceived as important factors that facilitate CE among SMEs. The study’s findings enrich our understanding of the contingent nature of entrepreneurial activity, suggesting that African context matters. It also adds to the growing body of literature on the importance of entrepreneurship in Africa
